Default command level
1: Monitor level
Parameters
slot slot-number: Specifies an IRF member device by its member ID.
Usage guidelines
This debugging command enables both IRF topology debugging and master election debugging.
Examples
# Enable all types of STM debugging on the IRF fabric. When a subordinate device receives a master
election notification message, output similar to the following example is generated:
<Sysname> debugging stm all
*Apr 26 22:15:19:840 2000 H3C STM/4/ROLE PACKET:Slot=8;Receieved election packet.

debugging stm topology
Use debugging stm topology to enable IRF topology collection debugging.
Use undo debugging stm topology to disable IRF topology collection debugging.
Syntax
debugging stm topology { all | error | event | packet } [ slot slot-number ]
undo debugging stm topology { all | error | event | packet } [ slot slot-number ]
